To all whom it may concern: I

Be it known that I, Josnrn E. PERRAULT, citizen of the United States, residing at Belmont, Massachusetts, have invented certain new and useful Improvements in Means for Efi'ecting the Union of Layers Having Adhesive Surfaces, of which the following isa specification.

My present invention relates to an improved method of joining together layers or articles of adhesive material such, for example, as layers of unvulcanized rubber or rubber having incorporatedtherein fabric or the like, or fabric coated with rubber known to the trade asfriction fabric, and also an apparatus for carrying out said method, and the invention includes the novel apparatusfor performing the same hereinafter described and particularly defined by the appended claims. A form of apparatus suitable for carrying out this method is illustrated in the accompanying drawings, in which- Figure 1 is a sectional elevation; Fig. 2 is an end View; Figs. 3 and 4; are detail views. I

According to my improved method the layers or articles of adhesive material to be joined are superimposed upon each other, andsimultaneously subjected to a rolling pressure and a vibratory movement imparted by giving a vertical reciprocation to either the article orthe mechanism by which the rolling pressure is imparted. I have found a most convenient manner of carryingout the method is to provide a vertically i-eci}' 1'ocating roller, and to move the articles or layers to be joined at right angles to the plane, of reciprocation of the roller. It will be'obvious that this method might be carried out by hand manipula-- tion, to witzby supporting the layers or articles upon any convenient support and manipulating the roller by hand through the required movements, but it would be difficult by hand to get the requisite uniformity of movement, andproper; pressure at all times, and I have therefore devised a machine capable of carrying out the method in simple and expeditious manner. In the accompanying drawings which illustrate such a machine, I'have shown it was adapted to apply the rubber soles to boots and shoes, but it will be obvious that it will be applicable to securing together any adhesive material by merelychanging the form of last or core, and in some instances modifymg the character of mechanism for ed by' a supporting member 2 which: has a projection 8 engaging the usual recess in the; heel portion of the last, and a seat 4 of proper shape for supporting the toe. These supporting parts are carried by or form part of a carriage 5 mounted to reciprocate horizontally upon guide rails 6 supported from the main frame 7 10f the machine, and the reciprocating motion of the carriage is effected by means' herein after more particularly described to cause it to pass under the roller or rollers which impart the rolling and vibratory pressure to the sole. I prefer to provide a plurality of such rollers operated in sucy ssion, the first roll 8 being a substantialy straight faced roll and operating in contact with the central portion of th outsole, and following this a pair of rollg 9 arranged at an angle of approximately 15, outer ends depending beyond the roll 8, thus making contact on the outsole where the roll 8 does not, especially on or near the edges of the outsole.

and with their These rolls 8 and*9 are carrier respectively by forks or yokes I 10 and 11 having their upper ends carried by eccentric shafts 10 and 11, which are ournaled in bearings carried by the lower ends of slides 12 and 13. These slides are by belts. and 11 and passing over pullevs 18, 19 and 20, and

connected to a bell crank lever 21 adapt-l led to be operated by the completion of its forward or working movementso as tolift'the rolls clear of the surface of the outsole on the return 1 movement of the carriage.

carried by the upper ends of the slides, and

driven by horizontally extending bolts 10.,

and 1 1 passing over suitable pulleys eon-' nected with the pulleys 10 and 11?, and over suitable; drivel pulleys on the drive shaft22 which'may be driven from any suitable source of power as, for instance, by -fb el l; 22* from main drive shaft 23.

a screw shaft 24 journaled in the frame of the machine, and'engaging a suitable nut or half nut connected with the carriage. The screw shaft is connected by gears 25 and-.26 with a countershaft 27 which, in turn, is connected b two sets ofgears'inclicated at 28 ,v and 29, one set of. which constitutes reversmg gears), with the clutch members 30' and 3l loose on shaft 32, which shaft is driven through worm 33 and Worm gear 34 from the main power shaft 23 by belt 3? and pulleys 36 and 3'2 as shown. Spiined on shaft- 32 is; a double faced clutch member 38 v whicl1,-when in one position, couples the direct gears 29 with the counter-shaft, and in the other position couples the shaft 32 with the screw shaft 24 through the reversing gears,

thus eiifectingthe return movement of the carriage. This clutch is adapted to be opi=0 erated by a pivoted clutch f0rk39 connected by a rod 40 to a pivoted arm ll at the ex- 7 tremeleft of the machine (Fig, 1 adapted as v 'ment by spri ng 41 so-that the upper portion of the arm can yield, if necessary, and

to cooperate with a lug 42 connected with the carriage. Thearm'il is composed of two parts hinged together, and held in aline revent any strains due to otherwise inelass j 't ic connections.

uponi Thereafter the mcveinent of the the carriage after The carriage 1s given its reciprocating movement by 'hesive surfaces comprising hand lever 45 releasesthe lever 46, allowing the same to drop and throw the movable clutch member into engagement with the clutch member 31.-

I find it desirable to provide in connec tion with the carriages or slides, of the vioratory rollers 8 and 9 lift rolls l7 and 48 which are elevated suiliciently. above the lower snrfaceso'f the rolls 8 and 9 to contact 13, bracket 47 and roller 4'? being omitted from Fig. 2' for more clearly illi'istrating roller 8'. I also find it desirable to provide a pair of non-vibratorg rolls 50 arranged at an angle substantially asshowmand carried by pivoted arms 51 drawn toward each other "by a spring 52, thereby producing a bearing action on the-edges of the outsole and wrapping' it firmly over the edge of the last.

Any suitable means may be employed to hold the frame 14 elevated during the return movement of the carriage, but a convenient means for accomplishing this purpose'is to connect to one of the rods 15 an arm 15 to which is connected a piston working in a dashpot 15, the action of which may be timed to hold the rods elevated and thus the rolls out of contact with the work during the i return movement of the carriage. The

function of the dash pot is simply to prethe bell crank is freed from the carriage the slides would drop immediately unless some means were provided to hold them elevated until the carriage has returned to initial V sition, and this is accomplished by the dash pot. V
